Go to training mode and select "Shooting Range". When in the shooting range, select any weapon that you want while in your armor. Next, go to "Favorites" and save inventory. Exit training mode and go to terminal. Select "Favorites" and choose the inventory you saved. You should have your weapons.

Pulling vehicles out of the warpgate

If there is a vehicle inside the warpgate that has no driver, back up as far as you can in a vehicle. Ram the other vehicle at full speed. A glitch in the game will allow the vehicle to cling on to your vehicle.

Fire through an enemy warp gate

You need somebody to fly you over an enemy sanctuary warp gate. Then, bail. You cannot do this yourself because the game will not allow you to bail out of your own plane over a warp gate. You have to go slightly to the side of the warp gate, to where the long metal part goes down (not too close or you will fall off). Look down and you can shoot inside of it.

Gliding character

At any time during the game, switch to the third person view of your character and start moving forward. While moving forward, double-tap forward again and your character should begin gliding. This may take a few attempts.
